When it comes to solar capacity, I tend to over-do it, mostly because:
1. the cost difference is not that great
2. The weight is more but still very manageable, and
3. In less than ideal conditions, 200w panels in filtered or partial sun simply push more power than the 100w case.
We have a 200w Renogy suitcase and I am very happy with it. I use the clips for greatest effective reach, but the box is set up with the gopower connector, which must be reversed for the Renogy cable.
